KltLBQURN; 0F GREENFIELD, "JZAESAJCEHUSET'X'S.

AUTOMATIC notification filed April 9, 1913.

and site of Massachusetts, have invented certa n new and useful Improvements 1n Anton? Carriage Returns for Type- Wri Machines, of which the following 1s cation.

i-vention relates to typewriting inachines, r 1d has particular reference to the carriage hich supports the p i'er platen.

The rncipal object o the entice is to provide means for automatically returning the carriage to the right when a new line of a speci This Writing is to be commenced.

A hirther object is to effect the actuation Of the platen to feed the paper,-siinultaneously with the actuation which results in the automatic return of the carriage.

A further object is to provide means ploy-ed to erl ec't the travel of the earrings to the left may be dispensed with, the step by,

step feed of the carriage toward the leftwhen Writing or sgaacing, being effected by the manual operation of the finger levers or keys, or the space bar. 7

To this endthe invention. consists in the irovenients which I shall now proceed to deer we and claim.

key or space bar 23 is carried by theusual arms or levers 24, said arms or levers and also the finger levers or keys being pivoted on the usual rod 25. Extending transversely of the typewrfling-machine, under the levers 22, .24, is the cross-bar 2e, connected by links 27 (Fig. with an upper bar 28 rigidly connected to one arm of an elbow lever 29, 30, of the kind which is usually er eyed for controlling the step by step feed of the carriage under the influence of the usual spring which spring, however, with my oresent iur provements, may be omitted, as hereinafter described.

A spring 31 is connected to the elbow lever 29, 80, to exert a tension on said lever to swing it in the direction opposite that of the arrow in Fig. 1, and in the direction to raise I will now proceec. to the specific description of my improvements. Avertical guide rod is rigidly scour: us by having its lower end stepped firmly in a rear portion or the base of: the frame, a. weightframe 83 being mounted to slide vertically on said guide-rod. In the embodiment of the inven tion illustrated, the weight frame includes a piece of sheet metal, but I do not limit myself to the use of sheet material. The weight has inclined edge rails'3 t, 35, (Fig. 3), the lower end of the former terminating in a hoolcshaped end. and theupper end of the rail 35 terminating in a hook-shaped end 37. Guide wheels 38 engaging the rod 32 are carried by brackets 39 secured to the weight. Said weight may have a pocket 4:0 for the reception of any suitableniaterial to variably increase the weight of the vertically movabl v rails 3e, 35. The weight as a whole,

has secured thereto a vertical ratchetrack 41,

stood that vertical movements of the weight frame, between the full and ddt'tcd line po tion shown in F 1g. 3, will cause the car to do so, or is actuated by the pawl mechanism Which I shall now describe.

The upward me ses weight in the manner just described, the rotation or the platen roll to feed the paper may be simultaneously effected. To do this I employ a fiat bar 60 normally occupying the posit-ion shown in Fig. 1, behind the lower end of the handle 19,] Said bar is carried by two arms 61 (Figs. 1 and 2) ivot-ed to the base ol' frame at 62. A slice plate 63 has arms 64; provided with pins engaging slots 35 in the lower ends of the arms 61. center rod 66 is connected to the slide plate 68 and projects through the front rail of the base ofthe frame o-i'tlie machine, and has a linger push 61in close proximity to the finger push 58, as-shown in Fig. 4, ';A spring 68 holds the parts just, described normally in While the operator may at any tune actuate the finger 'push -58 alone'to release the weight, by simply pressing the thumb or finger against both of the push pieces 58, 67 the list bar 60 will be caused to actuate the lever 17 by engaging the lower end of the handle 19, regardless of the lateral position of the latter. Oi course,'tl1e push piece 67 -may be alone actuated whenever it is desired to do more or less line s Jacin' or feed have provided means whereby during the operation of the type levers, or the s ace key or bar, energy 3.5 stored up by the li ting of the weight, said energy being then dagable of being utilized by releasing the weight which then acts asan impeller, to automatis oally urge the carriage toward the right, or

to position ,to begin a new line, and of course,

it will be understood that whenever desired, the energy stored up in the weight may be manually released. by operatlon of sold rod '57, and as has been explained, the gradual v .lt is to be UXKdGFSl EOOCl that while the draw mgs illustrate my improvements in connection with a writing machine of not the most recent type, I do not limit myself thereto, as

the improvements may be employed in connection with other and later types of visible writing machines,

I claim:

11.",lhe combination with-s typewritingmachine having a carriage provided with a rearward extension, of a vertically movable impeller having an inclined rail. engaging said extension :tor'retnrning the carriage to position to begin anew line, and connec-, tions whereby the manual operation of the type-levers when writing will raise the impeller step by step,

2. The combination. with a typewritingmachine having a carriage provided with rearward extensions, of an impeller movable in a path at an angle to the plane of travel of the carriage, said impeller having inclined rails-engaging said extensions, and connections whereby the manual operation of the type-levers when writing will raise the impeller stepby step. t

3. The combination with a typewritingmachine having a carriage provided with rearward extensions, of an impeller movable in a path at an angle to the plane of travel of the carriage, said impeller having inclined rails engaging said extensions, connections whereby the manual operations of the type-levers when writing will raise the impeller step by step, means for manually releasing the impeller at any point of its elevation, and connections whereby the'descent of the impeller will return the carriage to begin a new line.

4. The combination with a typewritingmachine having a. carriage provided with rearward extensions, of an impeller movable in a path at an angle to the plane of travel of. the carriage, said impeller having inclined rails engaging said extensions, con.- neetions whereby the manual operation of the type-levers when writing will raise the\ impeller step bystep, and means for 1nanually releasing the impeller at any point of its elevation and simultaneously line-spacing the paper, whereby the descent of the impeller will return the carriage to. position to begin a new line.

5. The combination with a typewritingmachine and the carriage thereof, of means for returning the carriageto position to begin anew line, said means comprising a vertically movable impeller having an inclined rail, and a wheel connected to the carriage and engaged by the inclined rail.

by step when the fingerkeys or the space-bar of the machine are operated.

7. The combination with (a typewritingmachine and the carriage thereof, said carriage being provided with wheels, of a vertically movable impeller having edge rails engaging said wheels, a. ratchet rack connected to said impeller, a lifting pawl en-- gaging said ratchet, and connections for actuating the lifting pawl by the finger keys of the machine. 4
